Boiling River Trail is located in the Mammoth Hot Springs area near the north entrance of Yellowstone National Park. An underground discharge of water from a mysterious source beneath nearby hydrothermal terraces flows out of the ground at over 100 degrees.
Generally, surface water works its way down to an average depth of around 2,000 metres (6,600 ft) where it contacts hot rocks. The resultant boiling of the pressurized water results in the geyser effect of hot water and steam spraying out of the geyser's surface vent (a hydrothermal explosion). At least 1,283 geysers have erupted in Yellowstone National Park, Wyoming, United States, and an average of 465 geysers are active there in a given year.
